Installation problem

[zxfever]

Following the installation, run GIT_LFS_SKIP_SMUDGE=1 uv sync
but the error is

No solution found when resolving dependencies for split
  │ (python_full_version == '3.11.*' and sys_platform == 'darwin'):
  ╰─▶ Because there are no versions of pyav and lerobot==0.1.0 depends on
      pyav>=12.0.5, we can conclude that lerobot==0.1.0 cannot be used.
      And because only lerobot==0.1.0 is available, we can conclude that all
      versions of lerobot cannot be used.
      And because openpi depends on lerobot and your workspace requires
      openpi, we can conclude that your workspace's requirements are
      unsatisfiable.

      hint: The resolution failed for an environment that is not the current
      one, consider limiting the environments with `tool.uv.environments`.

I checked the file uv.lock, it seems that the code is suitable in MacOs and Arm, but no x86_64

resolution-markers = [
    "python_full_version < '3.12' and sys_platform == 'darwin'",
    "python_full_version < '3.12' and platform_machine == 'aarch64' and sys_platform == 'linux'",
    "python_version < '0'",
    "python_full_version < '3.12' and platform_machine != 'aarch64' and sys_platform == 'linux'",
    "python_full_version < '3.12' and sys_platform != 'darwin' and sys_platform != 'emscripten' and sys_platform != 'linux'",
    "python_full_version < '3.12' and sys_platform == 'emscripten'",
    "python_full_version == '3.12.*' and sys_platform == 'darwin'",
    "python_full_version >= '3.13' and sys_platform == 'darwin'",
    "python_full_version == '3.12.*' and platform_machine == 'aarch64' and sys_platform == 'linux'",
    "python_full_version >= '3.13' and platform_machine == 'aarch64' and sys_platform == 'linux'",
    "python_full_version == '3.12.*' and platform_machine != 'aarch64' and sys_platform == 'linux'",
    "python_full_version >= '3.13' and platform_machine != 'aarch64' and sys_platform == 'linux'",
    "python_full_version == '3.12.*' and sys_platform != 'darwin' and sys_platform != 'emscripten' and sys_platform != 'linux'",
    "python_full_version >= '3.13' and sys_platform != 'darwin' and sys_platform != 'emscripten' and sys_platform != 'linux'",
    "python_full_version == '3.12.*' and sys_platform == 'emscripten'",
    "python_full_version >= '3.13' and sys_platform == 'emscripten'",
]

The code can not run in X86_64 platform?

hey bro, you can refer to this link in official openpi repo
Physical-Intelligence/openpi#472 (comment)

It works for me

[Musemote-Wang]

I guess the reason for this issue lies in that this project is based on an old version of lerobot. The old lerobot had a dependency on pyav, but pyav is now called av. You can refer to https://github.com/Physical-Intelligence/openpi/issues/472 for more details.

To address this issue, I copied the source code of lerobot with version "6674e368249472c91382eb54bb8501c94c7f0c56" to "./packages", and then modified line 57 of ./packages/lerobot/pyproject.toml to "av==12.1.0". Afterwards, I modified line 62 of ./pyproject.toml to "lerobot = { workspace = true }" to install lerobot from local source. This works for me.

I can confirm a working workaround: point lerobot to my fork (patched to avoid the pyav>=12.0.5 resolution issue).

In pyproject.toml:
change the lerobot source to:
[tool.uv.sources]
lerobot = { git = "https://github.com/XiequnWang/lerobot", rev = "8c00d474e00ea95dfa2095e223e931f91df4f4fb" }

Then rerun:

rm -rf .venv uv.lock
GIT_LFS_SKIP_SMUDGE=1 uv sync

This unblocked uv sync for me in an environment where the first index doesn’t provide a compatible pyav version.
